{
  string mySelectQuery = "SELECT * FROM NONEXISTINGTABLE";
  SQLiteConnection sqConnection =
    new SQLiteConnection(
        "DataSource=mydatabase.db;");
  SQLiteCommand sqCommand = new SQLiteCommand(mySelectQuery,sqConnection);
  try
  {
    sqCommand.Connection.Open();
  }
  catch (SQLiteException myException)
  {
    MessageBox.Show("Message: " + myException.Message + "\n");
  }
}

Public Sub ThrowSQLiteException()
  Dim mySelectQuery As String = "SELECT * FROM NONEXISTINGTABLE"
  Dim sqConnection As New SQLiteConnection( _
    "DataSource=mydatabase.db;")
  Dim sqCommand As New SQLiteCommand(mySelectQuery, sqConnection)
  Try
    sqCommand.Connection.Open()
